Update institutional contact information shown in unavailable layers alert

[thatbudakguy]

We'll soon be adding some layers that are from institutions we haven't included before:

• [x] Purdue
• [x] Illinois
• [x] Rutgers
• [x] Penn State
• [x] Ohio State
• [x] Chicago
• [x] Nebraska
• [x] Colorado State
• [x] Arizona
• [x] Virginia Tech

For each of these, we need a department and a contact email to list in our config: https://github.com/sul-dlss/earthworks/blob/0c42b2d512e32a190633888e13f3dea6dc1d96b9/config/settings.yml#L125

...which powers this message when layers aren't available for download or preview:
